[yashshah7197]

Any hints as to when we can expect this to be added?

[Hassan-Fa]

i'm not sure if i don't know how , or it's just not possible
but i couldn't get a shape to be applied to a mapView as background ( I mean even for another parentLayout that contains it )
any help ?

sorry if it's not a good place to ask , i hoped if it's not possible directly you could suggest a workaround

is there any alternate way/plugin to implement this?

There is an example here: https://codelabs.developers.google.com/codelabs/mdc-104-java/#0

I made a library (android only) for backdrop. It works fine, but need improves:

Is there any ETA on this and other components under development? I don't seem to be able to find any mention of the timeline except for the "Under Development" tag on the Material web site 😅

[pedromassango]

@Hackertronix For now all you can do is wait... Or try out my lib (if you wish) 😅

[DASAR]

Please give us at least timeline when to expect this component. We as developers should decide wait or implement this on our own.

Another implementation: https://github.com/ZieIony/Carbon/blob/master/carbon/src/main/java/carbon/widget/BackdropLayout.kt
It's pretty much a layout with a slide animation for one of its children.

[yashshah7197]

I guess we aren't getting this anytime soon as per this comment on #203. Probably best that we close this issue for now.

[jorgeperezruiz]

Any news on this? The material design guidelines says the implementation is available but once you go to github it still says it is not completed yet.

Thanks.

[ldjcmu]

We currently have no plans to implement this. I will look into the guidelines error.

[petitJAM]

@ldjcmu While you're in there, the iOS component is show as available in the guidelines but appears to not be implemented either.

[MatriscianoSalvatore]

Our implementation here:
https://github.com/keikenofficial/keiken-android/tree/master/app/src/main/java/com/keiken/view/backdrop

[amjad-alwareh]

It's been 2 years since this issue has opened.
Is there any ETA?

[petitJAM]

@amjad-alwareh It's not happening :disappointed:: https://github.com/material-components/material-components-android/issues/90#issuecomment-490926277

Though to be fair, this one's not too hard to implement anyway. You should be able to find some tutorials around the internet.
